Abstract:

This data represent a snapshot, or instant in time, from the cosmology simulation. This snapshot was taken at a redshift of
1.1, which is 5.4 billion years after the Big Bang. At this point, the simulation had created 263,398 grids and 1,107 galaxy
clusters with masses of at least 10^14 solar masses.
The primary contents are the parameter files, hierarchy file (description of grid sizes and spatial locations), and grid data.
For a complete description of the contents, refer to the Scope and Contents note for the collection.
In the Derived Data subcomponent, there are text, binary, and images files representing halo properties and the projections
of various physical fields.

Type:

Research data

Technical Requirements:

The parameter files are plain text, and can be accessed using a text editor or web browser. The complete snapshot is contained
in an archive file in the <a href="http://en.wikipedia.org/wiki/Tar_%28file_format%29">tar file format</a>. Within the archive,
the parameter and manifest file are plain text, while the grid files are binary files in the <a href="http://www.hdfgroup.org/HDF5/"HDF5
format</a>. Accessing the grid files requires either the HDF5 libraries or utilities.
N.B: This only provides access to raw values; an additional layer is required to build the Enzo data model (e.g., YT).
